Aluminum-27 nuclear magnetic resonance study of aluminum(III) interactions with carboxylate ligands

Aluminum-27 NMR in high field has been employed in aqueous solution, at 10 mM concentration, for the study of the interactions of Al(III) with citrate, lactate, and ethylenediaminetetraacetate (EDTA). In the reaction with lactate, slow-exchange phenomena make possible the observation of distinct peaks for hydrated Al(III), 1:1 and 1:3 Al-lactate complexes, as well as mixed aquo-lactato and hydroxo-lactato complexes. Increasing pH leads to substitution of water in the Al(III) coordination sphere by lactate and eventually to substitution of lactate by hydroxide. A 1:3 Al(III)-lactate complex produced in the presence of excess lactate remains in a metastable condition and does not readily dissociate when more Al(III) is added. Increased pH has similar effects on the reaction of Al(III) with citrate, but the reaction with EDTA leads to only one peak that corresponds to a very stable complex; apparently no mixed aquo-EDTA or hydroxo-EDTA complexes can be observed.
